ULTRASONIC CLEANING METHOD

摘要

Disclosed is an ultrasonic cleaning method that, at the very least, cleans an object to be cleaned by immersing the aforementioned object to be cleaned in cleaning fluid that is within a cleaning tank and transmitting ultrasonic waves generated from an ultrasonic transducer to the cleaning fluid that is within the aforementioned cleaning tank, and is characterized by the cleaning of the object to be cleaned by means of the ultrasonic waves generated by the aforementioned ultrasonic transducer being performed under at least two ultrasonic output conditions. As a result, an ultrasonic cleaning method is provided that resolves the problem of uneven cleaning (missed spots), which has been a problem with ultrasonic cleaning, and that can effectively eliminate particles.
